    #mv weathermap /usr/local/wwwroot/cacti/plugins/
    #chown -R apache.apache /usr/local/wwwroot/cacti/plugins/weathermap
    对weathermap的配置文件进行修改
    #cd /usr/local/wwwroot/cacti/plugins/weathermap
    #chmod u+w config/
    #cp editor-conifg.php-dist editor-config.php#vi editor-config.php
    $cacti_base = "/usr/local/wwwroot/cacti";
    $cacti_url = "http://222.186.43.15/cacti";
    $mapdir= $cacti_base .' /plugins/weathermap/configs';
    $ignore_cacti = FALSE;
    将editor.php中的ENABLED=false修改为true，否则weathermap点击Editor时会报错
    #cd /usr/local/wwwroot/cacti/plugins/weathermap
    #vi editor.php
    //$ENABLED=false;将false修改为true
    $ENABLED=true；
    点击console ->Plugin Management->在Actions处启用weathermap，至此weathermap插件安装完成。
syslog插件的安装
1.安装syslog-ng服务
    #rpm -ivh syslog-ng-2.1.4-1.el5.i386.rpm
2.安装syslog插件
    #tar zxvf syslog-0.5.2.tar.gz
    #mv syslog /usr/local/wwwroot/cacti/plugins/
    点击console ->Plugin Management->在Actions处启用syslog
    进入"User Management"->点admin->Realm Permissions->勾选View Syslog和
    Configure Syslog Alerts / Reports
    #mysql -uroot -p
    mysql>create database syslog;        创建一个数据库供syslog使用mysql>use syslog;
    mysql>source /usr/local/wwwroot/cacti/plugins/syslog/syslog.sql   导入mysql数据库mysql>grant all on syslog.* to cacti@localhost identified by 'cacti';添加一个数据库账号cacti 密码为cacti用以访问syslog库mysql>flush privileges;
    #cd /usr/local/wwwroot/cacti/plugins/syslog
    #vi config.php
    $syslogdb_type   = 'mysql';
    $syslogdb_default = 'syslog';
    $syslogdb_hostname = 'localhost';
    $syslogdb_username = 'cacti';
    $syslogdb_password = 'cacti';
    #vi /etc/syslog-ng/syslog-ng.conf 在最后末尾添加如下：
    source net {
    udp();
    };
    destination d_mysql {
    pipe("/tmp/mysql.pipe"
    template("INSERT INTO syslog_incoming (host, facility, priority, date, time, message) VALUES ( '$HOST', '$FACILITY', '$PRIORITY', '$YEAR-$MONTH-$DAY', '$HOUR:$MIN:$SEC', '$MSG' );\n")
    template-escape(yes)
    );
    };
    log { source(net); destination(d_mysql); };
    log { source(s_sys); destination(d_mysql); };
完成之后，执行
    #service syslog restart
    #service syslog-ng restart
在syslog插件目录下，编辑一个新的sh文件/plugins/syslog/syslog2mysql.sh，并且赋予可执行权限（同时该目录下
syslog_process.php也必须有可执行权限）：
    #vi /usr/local/wwwroot/cacti/plugins/syslog/syslog2mysql.sh 输入
    #!/bin/bash
    if [ ! -e /tmp/mysql.pipe ]
    then
    mkfifo /tmp/mysql.pipe
    fi
    while [ -e /tmp/mysql.pipe ]
    do mysql -u root syslog < /tmp/mysql.pipe >/dev/null
    done
运行syslog2mysql.sh，如果没有任何显示，后台有该进程，则基本上成功了。在/etc/crontab中添加：
    @reboot /usr/local/wwwroot/cacti/plugins/syslog2mysql.sh
    */1 * * * * php /usr/local/wwwroot/cacti/plugins/syslog_process.php
使开机执行syslog2mysql.sh，每分钟执行一次syslog_process.php
